Title: Fiber type optical amplifier
Inventor: MIZUOCHI TAKASHI
IPC: H04B10/564
Filed: 1990-01-08
Abstract: PURPOSE:To hold the level of an output signal constant even when signal light varies in level by providing a comparator which inputs and compares the output signal of a photodetector with a specific level and outputs an error signal and attenuating the signal light of an optical fiber according to the error signal. CONSTITUTION:An optical coupler 3a inputs a part of the signal light of the optical fiber 1. The photodetector 7 converts a part of the signal light received through the optical coupler 3a into an electric signal. The comparator 8 compares the output signal of the photodetector 7 with the specific level and outputs its error signal. A variable optical attenuator 9 attenuates the signal light of the optical fiber 1 corresponding to the error signal. Consequently, even if the inputted signal light varies in level, the amplification gain is controlled automatically and the output signal with the constant level is obtained at all times.

Filed: 1979-01-12
Abstract: PURPOSE:To prevent the decrease of the strength of parts due to the evaporation of water and maintain the bonding strength thereof for a long period of time by using a sintered body of a high porosity as a base plate. CONSTITUTION:The bonded surface of a base plate 2 is subjected to mirror surface working of less than 0.1S, and in the case of bonding, water is impregnated in the inner part of the base plate 2. Since the inner part is of a porous composition, when water is contained in the base plate, it is impregnated in its interior by a capillary phenomenon. At least the bonded surface of a work 1 is worked into a mirror surface, and water is applied in bonding of the work 1 to the base plate 2.

Title: Input device
Inventor: MATSUZAWA KAZUFUMI
IPC: G06F3/047
Filed: 1985-01-11
Abstract: PURPOSE:To form an input part with a high density and reduce detection errors of the input part by interposing an anisotropic conductive member between a pair of transparent substrate electrodes for input. CONSTITUTION:An anisotropic conductive film 4 which can be connected electrically to substrates by pressing only in the vertical direction is interposed between substrates I and II having transparent electrodes. For example, metallic particles are mixed in a transparent silicone rubber to obtain the anisotropic conductive member 4, and the member 4 is connected electrically to substrates by contacting of metallic particles due to pressing. The thickness of the transparent anisotropic conductive film is set to 100mu, and the transparent anisotropic conductive film is available if its contact resistance value is 300OMEGA for 50g/cm<2> pressure and is 200OMEGA for 10g/cm<2> pressure. Though the transmittance is 78% when the anisotropic conductive member does not exist, it is 64% to reduce the transparency slightly when the anisotropic conductive member is interposed; but all input required parts of an input device can be inputted because all of the surface is seen uniformly.

Title: Positioning device using microcomputer
Inventor: KOIWAI HIDEAKI
IPC: G11B21/10
Filed: 1979-01-17
Abstract: PURPOSE:To secure the high-accuracy head shift and then increase the record density of the VTR by installing the microcomputer which memorizes the error of the shift amount with every step of the fixed-head VTR and then giving correction to the error amount via the operation amount of positioning. CONSTITUTION:Prior to incorporation of the head tracking device, the error is measured via high-accuracy displacement measuring unit 21 for the shift amount of shifter 22 with every track to be supplied to the memory of the microcomputer. With designation of the track No. for the head, microcomputer 23 gives rotation to pulse motor 24 to generate the pulse number up to the designated address. The result of measurement is applied to the microcomputer and then supplied to memory 25 after calculation of the error amount. When the tracking device is incorporated into the VTR to designate the track, the fine adjustment is given through shift of the head and correction of the error amount via the pulse motor. In such way, the high-accuracy shift is ensured for the head.

When a rolling stock S is bitten by the rolls 15, in a state of slanting the rolls 15 oppositely to the advancing direction of stock S by a proper angle thetaeach, a moment is produced, which bends the stock S into a downward convex in the width direction. After rolling the stock S to some degree from its front end, the slant angle of roll 15 is reduced through the cylinders 19 to reduce the warped deformation. By this method, the width rolling reduction of stock S can be increased, and width accuracy and yield of the stock are improved.
